Specification of Letters Patent.

. Application filed June 10, 1913. Serial No. 772,864.

To all whom it may concern.

Be it known that I, JoHN FRANoIs OAKES, a citizen of the United States, residingat Copas, in the county of Washington and State of Minnesota, haveinvented certain new and useful Improvements in Bean- Harvesters, of which the following is a specification.

My invention relates to improvements in bean harvesters, and one object is the provision of a machine of this character which will bodily remove the complete vines with.

their crop of beans in a rapid manner without injury to the beans.

Another object of my invention is the provision of a machine of the character stated which can be easily drawn over the. ground and readily controlled by the driver for throwing the mechanism into and out of operation as circumstances require.

Another object of my invention is the pro vision of a bean harvester which will'comprise very few parts to produce a machine of simple, durable and inexpensive construction, which will stand hard usage and not be likely to get out of order, and which in general will be thoroughly eflicient and practical in every particular. With these objects in view my invention consists of a bean harvester embodying novel "features of construction and combination of parts substantially as disclosedherein.

In order that the construction in detail and the operation of my invention may be understood andits many advantages be fully appreciated I have illustrated in the accompanying drawing a bean harvester constructed in accordance with my invention.

Figure 1 is a top plan view of a machine embodying my improvements. Fig. 2 is a side elevation of the machine. Fig. 3 is a rear end view of the harvester. Fig. 4 is a sectional view on line l4t of Fig. 3, and Fig. 5 is a sectional view on line 5-5 of Referring by numeral to the drawings in which similar charactersof reference denote corresponding'parts in the severalviews of the drawings: The numeral 1, designates the frame of the machine, 2, the draftconnection, 3, the drivers seat, 4, the axle pass-' ing through the frame and 5,the ground or supporting wheels of the machine. Upon the axle between the side bars of the frame is mounted a yoke or bail 6 inthe cross portion 7 on which is journaled atone end a short longitudinal shaft 8 the other end of which is journaled in an upright 8 and which carries upon one end the bevel gear 9 and upon the other end thetoothed disklO and between said disk and cross portion 7 is eocentrically mounted. onsaid shaft the disk or wheel ll, said toothed disk and the eccentrically mounted disk providing the bean pulling or extracting devices of the bean harvester. The disk or wheel 11 is rotated with thetoothed disk 10, by the engagement ofthe bean ing action. :It will be understood that there is suflicientfriction betweendisks 10 and 11 to cause disk 11 to rotate upon the positive Irotation of disk 10,.but not in unison therewith. VVith'the bevel gear wheel 9, meshes the driving bevel gear wheel 12, mounted upon the axle and for the purposeofrais ing and lowering the yoke ing mechanism I employ the hand lever 13, shown depressed in Fig. 1 connected at its lowerend 14:, to the yoke andhaving a pin 15, which engages the teeth upon the under side of the rack 16, pivoted at its forward end to the bracket 18, and having a foot piece 19, for raising. said rack bar, which rack bar is provided with a sliding weight 20, which is adjustable upon the rack bar by means, of the pin 21, and openings22, in said rackbar.

From this construction it will be, observed that the lever for raising and lowering the yoke is arrangedadjacent the drivers seat where said lever can be instantly manipulated and alsothat the weighted rack bar will engage the lever and retain the bean extracting mechanism in the proper adjustment according to the relation of said mechanism with the ground andcrop of beans, and also that the eccentric mounting of the disk with reference with the toothed wheelprovides the space 23, which receives the vines as they are pulled from the ground and conveys the vines toone side where they are deposited and prevented from contact with the wheel by means ofthe plate or scoop 24, secured with the extract v Patented Sept. 29, 1914.

vines and said disksin their pull bytl ie hanger or bracket 25, with the frame,

and thebeveled 'vided with a guard or cover plate 26, which preventsforeignmatter from contact with said wheel to prevent clogging.

Theoonstruction and operation of the bean extracting or pulling mechanism being fully understood I will now describe the mechanism for operating the same; which gear wheel 9, s also. proconsists of the sliding clutch collar 27, havin' a s uare bearin 28 slidin" u Jon the operated to cause the axle when: revolved squared portion 29, of the axle and formed at one face with teeth 30, adapted when i shifted to engagethe teeth 31, formed upon theliub 32, of one of the ground n 'heels; in order that when the shifting lever 38', which hasthe forked end 34, engaging the clutch collar, is operated by the pivoted foot lever 35, pivoted at 36, upon the'frame and eonnected the link.37, with said shifting leverfsai'd clutch collar is thrown into engagement with the teeth on the hub and the ating the hand lever at the drivers' seat, as

will be readily understood; I t In use the mach'ne is drawn over the ground the bean extracting mechanism have v ing' been lowered to bring the toothed wheel near the'ground' andthe clutch having been:

to turn the driving gear wheel and operatc the bevel gear wheel upon the shaft carrying the toothed wheel, which toothed wheelas it; revolves by reason of the inclined or angulararrangement of its teeth draws the vines witha twisting action completely lifting said ,vines with their cro p of beans;fr om the earth' and thus in airapid andsefiioient manner pulling the vines with their beans and absolutely removing every vine inthe pathof said toothed ,wlieel, thus providing a machine which will rapidly remove the vines without injury to thebeans, whieh can be adjusted to suit conditions, which will stand the'liard work to which it is subjected and which will prove efficient and practical frcni every point of view.
